Kalo Gold expands Wainikoro epithermal system with quartz veins at Vatu Aurum
VANCOUVER, BC / ACCESS Newswire / July 8, 2026 / Kalo Gold Corp. (TSXV:KALO)(OTCID:KLGDF)(FSE:9M51) ("Kalo", "Kalo Gold" or the "Company") is pleased to provide an exploration update from Wainikoro within its 100%-owned Vatu Aurum Project, Vanua Levu, Fiji.
Ongoing soil geochemistry, prospecting, and trenching programs continue to refine drill targets across Wainikoro. Recent work has identified multiple mercury anomalies at the convergence of major regional fault structures, further supporting the Company's interpretation that Wainikoro represents a structurally controlled low-sulphidation epithermal system within the Nubu Graben corridor.
Key Highlights
Multiple mercury anomalies identified within recently completed soil grids, occurring near the intersection of two major regional fault structures interpreted as pathways for hydrothermal fluids.
Follow-up pitting has exposed previously unrecognized hydrothermally altered breccias and strongly altered andesitic volcanic rocks, with low temperature celadonite alteration indicating a preserved, high-level portion of a hydrothermal system.
Prospecting has discovered multiple new quartz veins across Wainikoro and within adjacent magnetic-low anomalies.
An outcrop sample of silicified altered andesite at the Wainikoro East magnetic-low target returned 5,505 detectORE™ units (dU) for gold - (~5.5 g/t Au estimated). The sample has been prioritized for Fire Assay confirmation (see Technical Notes on detectORE™ Gold Screening Results, below).
Ground geophysical surveys are being designed to further define structures and potential fluid pathways beneath cover.
Multiple independent datasets-including mercury anomalies, hydrothermal breccias, low-temperature alteration, quartz veining, pathfinder geochemistry and recent drilling-are converging on the same structural corridors, substantially reducing geological uncertainty and improving confidence in future drill targeting.
Mercury Anomalies Support the Epithermal Model
Recent soil programs have identified several discrete mercury anomalies within Wainikoro. These anomalies occur near the convergence of major regional structures interpreted to have acted as pathways for hydrothermal fluids during mineralization. Structural intersections of this kind can form dilational zones of enhanced permeability and are a recognized focus for fluid flow in epithermal systems.
Mercury is a well-recognized top-of-system pathfinder in low-sulphidation epithermal systems, concentrating in the shallow, cooler upper levels and lateral halos. Its presence is therefore consistent with a preserved, relatively un-eroded level of the system. This interpretation also suggests that any boiling or precious-metal zone may lie beneath the current level of exposure and therefore remains a priority exploration target.

Magnetic lows are outlined by blue dashed lines and vein and structural orientations are shown by orange arrows. The silicified, quartz-veined andesite sample that returned 5,505 dU (~5.5 g/t Au estimated) lies within a magnetic low adjacent to the Nubu Graben Fault.
Quartz Veins Expand the Target Footprint
Prospecting and mapping continue to identify quartz veins across Wainikoro, including within and adjacent to several magnetic-low anomalies defined by airborne geophysics. The association of quartz veining with magnetic lows is consistent with hydrothermal alteration (silicification and argillic alteration) destroying magnetite, making magnetic lows an important exploration vector.
An outcrop sample of silicified, microcrystalline quartz altered andesite (WKE-LR26-017A - Figure 2), collected on a traverse at the Wainikoro East magnetic-low target, returned 5,505 dU for gold - (~5.5 g/t Au estimated). The sample has been prioritized for shipment to ALS Limited (Australia) for Fire Assay confirmation. Other field samples collected across the area have also been submitted for Fire Assay.
Follow-up resampling of the same outcrop returned four further anomalous gold values across separate parts of the exposure - 3,228 dU (~ 3.2 g/t Au estimated), 1,406 dU (~ 1.4 g/t Au estimated), 1,376 dU (~1.4 g/t Au estimated) and 1,181 dU (~ 1.2 g/t Au estimated) (samples WKE-LR26-025A to WKE-LR26-025D) - reproducing a strongly anomalous response across four additional independent samples.
The growing distribution of quartz veining, hydrothermal alteration and pathfinder geochemistry suggests mineralizing fluids were active across a broader area than previously recognized and supports the interpretation that the Wainikoro hydrothermal system is more laterally extensive than previously recognized.
Next Steps
Kalo's exploration team is integrating geological mapping, soil geochemistry, prospecting results, drilling data, and airborne geophysical datasets to further refine priority targets across Wainikoro. Recent comparison of the airborne radiometric potassium survey against the Wainikoro soil XRF potassium data shows a strong spatial correlation, independently validating the field XRF results and reinforcing the interpretation of structurally controlled hydrothermal alteration along the fault and graben boundaries defined by the airborne magnetics.
Ground geophysical surveys are being designed to define subsurface structures, alteration zones and potential fluid pathways beneath shallow cover. These results will be integrated with existing geological, geochemical and drilling datasets to prioritize the highest-confidence drill targets across Wainikoro.
CEO Commentary
Terry L. Tucker, P.Geo, CEO of Kalo Gold, commented: "One of the most encouraging aspects of Wainikoro is that multiple independent datasets are beginning to point us toward the same areas. We are now seeing mercury anomalies, major structural intersections, hydrothermal breccias, low-temperature alteration, quartz veining and anomalous gold responses converging within the same target corridors."
"Mercury is a recognized top-of-system pathfinder, and together with the celadonite alteration it tells us we are looking at a preserved, shallow level of the system. The bladed-carbonate textures we logged in VA26-DH19, the gold values, and the arsenic corridors point to fertility - and they suggest the productive part of the system is a target at depth."
"Each day in the field improves the geological understanding of the target. As we integrate these results with the upcoming ground geophysical surveys, we are improving our ability to prioritize the structures and alteration centres most prospective for gold mineralization."
Technical Notes on detectORE™ Gold Screening Results
This news release references gold (Au) values reported in detectORE™ Units ("dU"), generated using the detectORE™ field-based gold analysis system developed by Portable PPB Pty Ltd. dU values represent a semi-quantitative, ppb-equivalent measure of leachable gold response and are used for exploration screening purposes only. They are not a direct measure of total gold content and are not equivalent to certified Fire Assay results. Accordingly, dU results are not used to estimate Mineral Resources or Mineral Reserves. The Company further cautions that detectORE™ readings can be affected by the presence of mercury, which may over-report the gold response; the 5,505 dU value referenced above is subject to such potential interference and remains an unconfirmed screening value pending certified Fire Assay.
Internal validation work conducted by the Company in 2025 on 824 samples from the Vatu Aurum Project demonstrated a strong correlation between dU values and certified Fire Assay results (Pearson R = 0.98 for drill core; R = 0.96 for trench samples). Soil dU results have not been directly validated against Fire Assay. While a positive relationship exists, it is variable across different ranges and may be influenced by lithology, mineralogy, and sample preparation. Any approximate equivalence (e.g. ~1,000 dU ≈ ~1 g/t Au) is provided for contextual reference only and should not be relied upon for grade estimation.
